I wrote an bash script which makes the SSH server configuration audit a little bit easier. Here now an description for usage. The repository can found here.

Usage

# upload script to target host (tmp directory)
$ scp ssh_audit.sh <user>@<host>:/tmp

# login into target host
$ ssh <user>@<host>

# switch to root
$ su -

# change file permissions (optional)
$ chmod u+x /tmp/ssh_audit.sh

# run ssh audit
$ /tmp/ssh_audit.sh

The output is self-explanatory. If you need more details, just run following command.

# output the effective configuration to stdout (Extended test mode)
$ sshd -T
